The Greatest Common Divisor is 1
The Greatest Common Divisor of two numbers is the largest number that will divide into both evenly. For example, although 27 and 81 are both divisible by 3, it wouldn't be the greatest common divisor, because 27 divides into 81 evenly as well: the greatest common divisor of 27 and 81 is 27.

Answer: 3Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 81 are 1, 3, 9, 27, and 81.The factors of 132 are 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, and 132.The common factors are 1 and 3. Therefore, the greatest common factor is 3.
The GCF is 9.
The Greatest Common Divisor of 297, 891, 2187 is 27.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 81 and 85 is 1
